Subject[PATCH v4] drm/panel: simple: add SGD GKTW70SDAD1SD
Date
Add support for the Solomon Goldentek Display Model: GKTW70SDAD1SD
to panel-simple.

The panel spec from Variscite can be found at:

v4:

- added the datasheet labels
- added Reviewed-by

v3:

- added flags
- added delay

v2:

- changed bpc to 6
- set max value of pixelclock
- increased hfront_porch and hback_porch
- dropped connector-type

adding of bus_format = MEDIA_BUS_FMT_RGB666_1X18 results in wrong colors.
omitting bus_format and using some default is better (Tux Pinguin is colored
fine)
